Dichloroacetic acid or DCA is an analogue of acetic acid. Salts of DCA may be used as drugs because they inhibit pyruvate dehydrogenase kinase and boost or restore the function of mitochondria (cellular power plants).
The most popular and researched form of DCA is Sodium dichloroacetate. The same form was used in pilot trials to evaluate whether this substance could improve the condition in those who suffer from ME/CFS. The first open-label pilot trial examined 22 patients (14 women, 8 men, mean age 43.3) suffering from long-lasting ME/CFS. The study found that 10 patients responded well, their score on the Fatigue severity scale decreased at least by 40%.
Soon after the trial, members from of a ME/CFS community forum also shared their experiences with the substance, some of them positive.
Molecular formulas[edit | edit source]
Uses[edit | edit source]
DCA, salts of dichloracetic acid, have been discovered in the 1960s. Since then the compound has been intensively researched. In 1983 it has been confirmed to be a potential remedy in treating congenital children mitochondrial disorders.
Up till now, dozens of studies have proven that DCA can be useful in managing illnesses such as elevated serum cholesterol and triglycerides, diabetes, amyotrophic lateral sclerosis, pulmonary arterial hypertension, chronic fatigue syndrome, endometriosis and cancer.
In 1989, Canada approved DCA for applying to the skin for treating warts and for "cauterization and removal of a wide variety of skin and tissue lesions", though this was cancelled post-market.
Currently DCA (Sodium dichlrooacetate) is approved in Canada as an orphan-drug, the only way of treating children with inborn mitochondrial-errors. It is also used off-label in alternative cancer clinics in North America, South America and Europe.
Theory[edit | edit source]
Sodium dichloroacetate is a molecule that can enter our cells. The living cells of most organisms have specialized structures that make chemical energy in our body, the mitochondria.
Once DCA enters the mitochondria, it inhibits the enzyme pyruvate dehydrogenase kinase. After this enzyme is halted, it stops blocking the pyruvate dehydrogenase enzyme. As a result this increases the energy output in our cells.
It is thought that many sufferers of ME/CFS have mitochondrial dysfunction resulting from epigenetic, immunologic and inflammatory factors. Restoring the function of impaired mitochondria could potentially alleviate the symptoms of this disease.
Evidence[edit | edit source]
Open-label pilot trial done in Belgium with 22 patients suffering from ME/CFS had favorable results. The Fatigue severity scale decreased at least by 40%.
Anecdotal evidence from the members of Phoenix Rising forum, the results range from none, to positive or dramatic improvement.
Risks and safety[edit | edit source]
Dichloroacetic acid is a strong acid and should be avoided for internal use. Instead, only salts or the most common form Sodium dichloroacetate should be used as its near the finish line of getting FDA-approved registration for other indications and has the most extensively studied safety data.
Formula used in the trials[edit | edit source]
DCA and its most popular form Sodium dichloroacetate were used in the trials. Both powder and capsules are acceptable. The DCA purity used in the pilot trial for ME/CFS treatment was 99.9%.
The full nutraceutical formula was never revealed, however, based on the available literature it looked something like this:
- DCA 400 mg
- Vitamin B1 (thiamine) 100 mg
- Alpha-lipoic acid 100 mg
- Oxidoreductase ubiquinone (Q10) 50 mg
The formula was taken for 30 days straight. However, if symptom relief is not achieved after a month, DCA could be taken 5 days straight with a 2 day break at the end of the week. Such cycles should be repeated every week for symptom control.
Nevertheless, additional trials are needed to draw further conclusions.
Costs and availability[edit | edit source]
DCA and its most popular form Sodium dichloroacetate is available in naturopath clinics, as an off-label drug in Canada or on the internet. It is a non-patentable generic drug that can be freely transported all around the world.
Daily dose of DCA with the additional supplements in the nutraceutical formula cost about $1-2 daily.

mitochondria Important parts of the biological cell, with each mitochondrion encased within a mitochondrial membrane. Mitochondria are best known for their role in energy production, earning them the nickname "the powerhouse of the cell". Mitochondria also participate in the detection of threats and the response to these threats. One of the responses to threats orchestrated by mitochondria is apoptosis, a cell suicide program used by cells when the threat can not be eliminated.
naturopath a practitioner who uses a system of treatment of disease that avoids drugs and surgery and emphasizes the use of natural agents (such as air, water, and herbs) and physical means (such as tissue manipulation and electrotherapy)
myalgic encephalopathy An alternate term that is sometimes used for myalgic encephalomyelitis, by people who believe the evidence for inflammation in ME is insufficient. This terminology reflects the belief that the "-itis" suffix implies inflammation.
myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
